php exec()未执行命令 [英] php exec() is not executing the command

问题描述

我尝试将exec()与'whoami'一起使用以检查其是否有效，并且得到了

I have tried to use exec() with 'whoami' to check if it works and I got the result of

nt authority\system

现在，我需要通过exec()函数使用php中的参数运行.exe文件.

Now I need to run a .exe file with parameters from php via exec() function.

我在命令提示符中尝试了此操作，它实际上以给定的参数运行程序.这是示例命令.

I tried this in command prompt and it actually runs the program with given parameters. This is the example command.

注意.exe文件获得3个输入(文件夹，file_name，report_file_nmae)

NOTE the exe file gets 3 inputs (folder, file_name, report_file_nmae)

> ..\..\some_file.exe folder="C:\path_to_folder" param=1.xml report=2.xml

但是当我从php文件运行此命令时:

But when I run this command from php file:

exec('..\..\some_file.exe folder="C:\path_to_folder" param=1.xml report=2.xml');

什么都没有发生.这是我第一次使用exec()函数，因此我对其细节不熟悉. 怎么了?

nothing is happening. This is the first time I am using exec() function, so I am not familiar with its details. What is wrong?

我尝试使用:

• \\而不是\
• escapeshellarg()在目录上
• 在目录文件夹名称周围添加了""

• \\ instead of \
• escapeshellarg() on the directory
• added "" around directory folder names

没有运气

附录:

echo exec($command)  // echos < .... why?

或

exec($command, $output);
print_r($output);        // Array()

我什至将文件的权限更改为对所有用户完全控制. 如果从command prompt调用程序，则可以看到时钟旁边的图标显示一秒钟.

I even changed the permission on the file to full control to all users. If I call the program from command prompt, I can see the icon appearing next to clock for a second.

但是从php进行的相同调用甚至不会调用该程序.

But the same call from php will not even call the program.

修改

即使exec('notepad.exe');无法正常工作.可能需要对php配置做些什么?

Even exec('notepad.exe'); is not working. Something has to be done with php configurations maybe?

推荐答案

我已经说过我是exec()函数的新手.经过更多的挖掘之后，我遇到了2>&1，需要在exec()的命令末尾添加它.

I already said that I was new to exec() function. After doing some more digging, I came upon 2>&1 which needs to be added at the end of command in exec().

也感谢@mattosmat在评论中指出.我没有立即尝试此操作，因为您说这是Linux命令，我在Windows上.

Thanks @mattosmat for pointing it out in the comments too. I did not try this at once because you said it is a Linux command, I am on Windows.

所以，我发现，该命令实际上是在后端执行的.这就是为什么我看不到它实际上正在运行的原因，而这正是我所期望的.

So, what I have discovered, the command is actually executing in the back-end. That is why I could not see it actually running, which I was expecting to happen.

对于所有遇到类似问题的人，我的建议是使用该命令. 它将指出所有错误，并告诉您有关执行的信息/详细信息.

For all of you, who had similar problem, my advise is to use that command. It will point out all the errors and also tell you info/details about execution.

exec('some_command 2>&1', $output);
print_r($output);  // to see the response to your command
